TRA News

This page is intended to note items of pertinent interest that may be occurring with TRA data and with industry activity that may impact TRA data.  Links to other sites may exist. Items will be added top to bottom.  Retention length of items may vary.   Information on this page will be updated as may be needed - this should not be considered a daily or weekly news page. Countless activities are occurring in the telecommunications industry daily and cannot all be listed here. Comments are appreciated. Two sections to this page exist:

• Future Area Code Splits in TRA Data
• News / Notes

Future Area Code Splits in TRA Data

Based on information provided to TRA on or before the database update date identified below, the following NPA (Area Code) split details (NPA NXXs) have been entered in the TRA databases via mass updates and will be reflected in the next issue of TRA products following these dates (the specific product dates for the monthly LERG and TPM are listed). The NNAG dates are the same as the LERG. Please note, for various reasons, split details are subject to change before and during the permissive dialing period (extent of changes will vary).  Also listed on this table may be cases where a split has been identified via a NANPA PL to be forthcoming, but for which data has not yet been provided to TRA or entered into TRA databases.  Splits that may have been announced but subsequently were suspended by the regulatory body having jurisdiction, are not listed.

This table represents geographic splits only, not overlays. Where splits may have multiple end dates for permissive dialing (e.g. for wireless), the primary (usually wireline) date is listed. Information will be retained on this table for a short time past the start date of the permissive dialing period of each split. Splits are listed in order of the start date of permissive dialing.

NANPA Planning Letters

Often related to Area Code activity, for your reference, the following Planning Letters (PLs), issued by the North American Numbering Plan Administration, were placed at the NANPA web site www.nanpa.com during the last completed calendar month.  They are noted here to keep you abreast of any new information.  However, check the NANPA site for the listing and availability of any past or late-breaking PLs.  In addition to NANPA PLs and News Releases regarding Area Code activity, Local Service Provider sites and Public Utility Commission sites often contain split related information. Commission sites can be reached by linking through www.naruc.org. The extent and timeliness of information may vary by site.

News/Notes

• LARG and CNARG will not longer be provided as 3.5 inch floppy diskettes beginning 09/01/08.  Recipients of the diskettes have been informed via a paper insert included with the diskette mailing of 06/01/08.  Email and web download options have existed for sometime.  Recipients of the diskettes should contact TRA at tra@telcordia.com to change their distribution media.
  
  
• LERG™  Routing Guide changes were effective 06/01/08.  A new file was added to provide postal codes for the localities identified in the LERG.   "TARGET" OCN fields were added to LERG1.  A sample reflecting these updates is available at this site (catalog page - LERG link) and by clicking here.  File specifications and a more detailed document reviewing the changes are available for download and/or review from the documents page of this site.
  
  
• LERG™  Routing Guide changes were effective 06/01/07.  This "change" simply modified how the database version of the LERG on CD is provided (i..e no file format changes).  To address CD capacity issues these files are now provided on the CD in a compressed self-extracting “zipped” file,
  
  
• The 04/01/07 NNAG in paper was the last version of the NNAG to be issued in paper format.  Decreased demand and increases in mechanized process of data by users has made the need for publishing the NNAG in paper report format obsolete.  Recipient contacts for the product in paper were notified 3 months in advance and provided alternate means to obtain the data
  
  
• LERG™  Routing Guide changes were effective 03/01/07. These changes involved the addition of a 20-character COUNTY field to the LERG8LOC file.  By having access to the county a given LOCALITY is in, counties associated with Rate Centers and NPA NXXs can also be determined.  In addition the LRNTYPE field was removed from LERG12 files.  File specifications and a more detailed document reviewing the changes are available for download and/or review from the documents page of this site.  Click here for a downloadable sample.
  
  
• The 12/01/06 LERG™  Routing Guide in paper was the last version of the LERG to be issued in paper format.  Decreased demand and increases in mechanized process of data by users has made the need for publishing the LERG in paper report format obsolete.   Recipient contacts for the product in paper were notified 3 months in advance and provided alternate means to obtain the data.
  
  
• As of the 4/15/07 product, Mexican data is no longer is provided in the OTCNPG.  Due to Mexican numbering plan changes referred to above for the TPM, Mexican numbering data is no longer provided in the OTCNPG after the 4/15/07 product.
  
  
• TPM™ Data Source product changes relative to Mexican data occurred with the 10/15/06 TPM (issued  09/06).  Mexico numbering plan modifications effective on or about 10/15/06 require the using of a 1 (one) following the country code when dialing Calling Party Pays (CPP) calls.  Mexican data in the previously existing TPM file format will was retained through the 4/15/07 TPM product to permit transition by users.  Beginning with the 10/15/06 TPM, a new file was provided for Mexican data under the revised format.  No other changes apply to TPM data or files beyond those noted as part of this update.  Click here for further information.  A sample is available for download.
